Re-anchorage of a ruptured tendon in bonded post-tensioned concrete beams: model validation [PDF]

, 2013
Many post-tensioned concrete bridges have been reported to have ruptured tendons due to corrosion [1] and the assessment of their residual structural capacity has to account for the possibility of re-anchorage of failed tendons.
